What Is a Definitive Agreement?
Everything before the definitive agreement, from the teaser through the letter of intent, is preliminary; the definitive agreement is where the deal becomes legally enforceable. Depending on the structure, it takes the form of a stock purchase agreement or an asset purchase agreement in private deals, and a merger agreement in most public company transactions.
Signing the agreement and closing the deal are usually separate events. The gap, which can run from weeks to many months, exists so the parties can obtain regulatory approvals such as Hart-Scott-Rodino antitrust clearance and satisfy other closing conditions like shareholder votes. The agreement also dictates how the business must be operated during that interim period.
Key Provisions of a Definitive Agreement
The economic core covers the purchase price and how it adjusts, whether through a working capital true-up at closing or a locked box mechanism that fixes the price off a historical balance sheet. Around that sit representations and warranties, in which the seller makes factual statements about the business, and covenants governing conduct between signing and closing. Closing conditions specify what must be true before either side is obligated to complete the deal.
Risk allocation provisions determine what happens when things go wrong. Indemnification clauses let the buyer recover losses from breaches in private deals, often backed by an escrow of roughly 5 to 15 percent of the purchase price. Termination provisions set the cost of walking away, including breakup fees payable by the seller and reverse termination fees payable by the buyer, while a material adverse change clause addresses a collapse in the business before closing.
Why the Definitive Agreement Matters
Negotiating the definitive agreement is where months of process crystallize into enforceable terms. Small drafting choices carry large consequences: the scope of a material adverse change clause or the cap on indemnification can shift tens of millions of dollars of risk between the parties, which is why negotiations over these pages can take weeks even after price is agreed.
Bankers do not draft the agreement, but they negotiate alongside counsel on the economic terms and must understand its mechanics to advise clients well. For interviews, know the sequence: the LOI leads to negotiation of the definitive agreement, and signing makes the deal binding while ownership transfers only at closing once all conditions are met.
